Debugging driver z program in ME31L or ME32L or ME33L

Hi Experts,

I need help on debugging driver program for adobe form for the tcode me31l or me32l or me33l.

Usually we have print priview option for the most of the tcode.but incase of me31l or me32l or me33l we dont have option called print preview.its directly going to spool file.

Now my requirement is to trigger breakpoint at my driver program .while creating or changing the scheduling agreeement document.

Thanks in advance.
